The Relationship Between Optic Nerve Sheath Diameter, Carotid Artery Pulsatility Index, And Blood Pressure In Healthy Adults, Rachel Marie Stone

Electronic Theses and Dissertations

Monitoring intracranial pressure (ICP) has become an important practice in patients with elevated ICP (e.g., traumatic brain injury) to improve patient outcome. However, little information exists surrounding chronic, but sub-clinical elevations in ICP, which may stem from classic cardiovascular risk factors, such as elevated blood pressure (BP). The current methods to assess ICP are invasive and costly; but optic nerve sheath diameter (ONSD) and blood flow pulsatility (pulsatility index; PI) are promising non-invasive techniques, both of which have been reported to strongly correlate with invasive measures of ICP in pathology. However, the interactions of BP, ONSD and PI in otherwise …
